Inspired by: https://github.com/pi-hole/pi-hole/pull/2112 A pre-start and a post-stop script are added to reduce doubled setup and cleanup code. Since systemd services do not natively support dynamic users, test once whether capabilities are supported during install/update, and remove User=pihole otherwise.

# This unit is supposed to indicate when network functionality is available, but it is only

# that is ordered after network-online.target will be stopped before the network

# A target that should be used as synchronization point for all host/network name service lookups.

# All services for which the availability of full host/network name resolution is essential should
|
|
# be ordered after this target, but not pull it in.
